bcfba2c167 Move a bunch of init code to Kernel::initialize()
- Kernel owns a MemoryManager, which is responsible for initializing the GDT.
- Kernel is passed a new StartupInformation struct (borrowed this one from
  Ghost) which contains a bunch of handy tidbits for setting things up.
- Cleaned out even more stuff from kmain()
2016-03-25 01:21:49 -04:00
